Non-Toxic, Eco-Effective Ice Pack

These reuseable, non-toxic ice packs are unlike the gel-based packs you may have used. Most ice packs on the market today contain urea, a waste byproduct. Instead these packs use a super-absorbant material instead. You can cut them to any configuration you need, soak them in water for a few minutes and freeze. The packs remain flexible when frozen, and they do not release the water once they thaw out

A simpler, even more eco-friendly idea can be assembled whenever you need an ice pack. Take a large ziplock freezer bag, and a kitchen dish towel. Fold the towel flat and insert in bag. Add water until the towel cannot absorb anymore. Zip closed and freeze. Works very well, and when the trip is over, the bag and towel have other uses. Our society has too many single-use products, which in and of itself is wasteful.

Hi there!
I’m doing some research for a school project about cold packs. I was wonderin if you could please help me with a question. the question is: If you were to take cold packs into space will they contribute the same way as on earth or will it be different?
Thank you!
